The goggle is specific to the wavelength of laser pointer

The goggle is specific to the wavelength of laser pointer .It is among all kinds of laser pointer 
The integrity of the nozzle: if the ring or part of the nozzle hole is not a rule is blocked (usually caused by metal shavings flying objects), will result in the disturbance of the auxiliary gas, cutting performance has significantly changed. The adjustment of the nozzle / beam: a focused laser beam must be coaxial with the nozzle hole, otherwise, the laser beam will be the nozzle blocking a part of. The lateral position of the lens by adjusting knob (in the lower part of the cutting head) to adjust, it is the lens mount module. The knob acting on the lens on the external optical path adjustment: a wide range of beam transmission outside of the mirror (laser) the need to always be adjusted. When the cutting head in the work area moves, the laser beam through the center of the lens. If the customer will not use laser pointer for a long time.CO2 gas laser of the incentives can be divided into the DC excitation, the exchange of high-frequency excitation, the RF excitation and microwave excitation. In the early stage of development of the CO2 gas laser, the excitation power used frequency step-up transformer, and then to DC rectifier, filter, resistor current limiting to maintain gas glow discharge. With the advancement of electronic components and electronic technology, the laser power the rapid development of incentives by the DC to AC high frequency excitation, to the hot RF excitation and microwave excitation. From the late 1970s, foreign high-frequency (HF) radio frequency (RF), microwave (MW) incentive industrial CO2 lasers. High frequency excitation or silent discharge (SD) high-power CO2 laser. The module of laser pointer utilizes the imported laser diode. The following detailed introduction to gas choice on many aspects of these areas, including the laser beam interaction, protection, efficiency, bead performance, and to transfer the standard gas mixtures and flow equipment. The hybrid laser processing technology will be a two energy incorporated into the weld pool area. Hybrid processing technology makes the advantages of laser welding to get specific, these advantages include welding speeds could be increased, the heat affected zone is restricted, narrow the welding seams at the same time has excellent weld appearance. GMAW as a secondary energy, it improves the overall process energy efficiency, reduce equipment costs and also improve the ability of the welding gap, in addition, it reduces the cooling rate, while improving the aluminum energy coupling efficiency.  laser pointer can burn the match very quickly and powerfully.
